In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a lifting device for overhauling a tunnel cable comprises a channel steel support, a groove box for fixing a jack and a hanging shaft; the vertical slotted hole is formed in the bottom surface of the right side of the channel steel support, symmetrical transposition holes are formed in the front side wall and the rear side wall of the channel steel support respectively, the hanging shaft is inserted into the symmetrical transposition holes, vertical plates on the front side and the rear side of the left end portion of the groove box are movably connected with two end portions of the hanging shaft, and the left end of the lower portion of the groove box is supported on the bottom surface of the right side of the groove steel support.
The invention is further improved as follows:
the quantity of channel-section steel support is more than two and butt joint from top to bottom, uses connecting plate and bolt fastening between the channel-section steel support, and the bottom that is located the channel-section steel support of lower part is equipped with the base.
Wheels and wheel pull rods are additionally arranged, and wheels and wheel pull rods are further arranged at the lower end parts of the channel steel supports at the lower parts.
And a horizontal jack is additionally arranged and is installed in the channel box through a fastening bolt, and a pressure rod of the horizontal jack extends out of a vertical slot hole in the channel steel support.
The cable support plate is additionally arranged, a plurality of arc grooves for accommodating cables are formed in the upper portion of the cable support plate, and a sleeve movably connected with the jacking head of the horizontal jack is arranged on the lower portion of the cable support plate.
The distance adjusting plate is added and is symmetrically connected to vertical plates on the front side and the rear side of the left end of the lower portion of the groove box through bolts, and the angle between the groove box and the channel steel support is adjusted through transverse displacement of the distance adjusting plate.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: according to the invention, the channel steel support is arranged on the ground of the tunnel, the groove box movably connected with the channel steel support is arranged below the cable, the horizontal jack is fixed in the groove box, the angle between the groove box and the channel steel frame plate is changed by changing the position of the hanging shaft through the transposition hole, and the angle fine adjustment can be carried out by moving the distance adjusting plate, so that the horizontal jack can lift the cable from different angles. The channel steel support is in butt joint up and down, so that the horizontal jack can lift cables at different levels. The cable maintenance device is simple in structure and rapid to assemble, facilitates moving in the tunnel to maintain the cable, can reduce labor intensity, guarantees construction safety, and improves labor efficiency.
